I did not sell special small hand taps like this one even if I looked for it at a local home center etc. When I tried searching it on the net, I arrived at the page of Monotaro, and I got a good impression that there was an explanation of the variety of kinds, and the explanation of the difference of the numerical value of the tap which I did not know before. I think that the display of dispatch on the day is also clear and very good. I will continue to use it.
